heal.abstract	The crystal structure and physical properties for (Y,Ce)2Sr2Cu2FeO8+y compound are reported using Rietveld-refinement of x-ray powder-diffraction data, dc magnetic susceptibility, Mössbauer, and Raman spectroscopy measurements. Mössbauer data can be analyzed with three components. Component A is attributed to Fe3+ (S=5/2) ions in the Cu(2) site. Component B is attributed to Fe3+ (S=3/2) ions in the Cu(1) plane and appears only in the oxygen saturated sample. For the reduced sample, component B transforms to component Dr, which has a lower oxygen coordination number with respect to that of component B. The Raman lines are assigned to definite atomic vibrations in close comparison with other compounds of similar structure. © 1995 The American Physical Society.	en
